Abstract
A polyester fiber comprises a hygroscopic polyester composition which contains 1 to 20 percent by weight of hygroscopic silica-based inorganic particles in which the average diameter, the specific surface area, the micropore volume, and the hygroscopic parameter ΔMR are within specified ranges. This hygroscopic fiber is suitable for clothes which require comfortableness.
